TIGER HEAD THLG3KW-6KW G1 Single-Phase Low Voltage Grid-Tied Hybrid Inverter, the Max. Input Power from 4500W-9000W. IP65 protection grade, suitable for outdoor work, fanless quiet design. Off-grid, grid-connected dual output, with air conditioning and other inductive load, and off-grid switching time is less than 20ms time, to achieve uninterrupted power supply.Adaptive lithium battery, battery and PV/AC system through the high-frequency transformer isolation, safe and reliable two-way DCDC due to the use of resonant soft switch ZVS technology and synchronous rectifier technology greatly reduce the switching loss, improve the charge and discharge efficiency. It is compatible with wired CT and electric meter to prevent countercurrent and prevent pollution to the power grid.
